The point where two axes meet is called?

The correct answer is Origin. In a Cartesian coordinate system, which is a fundamental concept in mathematics for defining points in space, the point where the perpendicular axes intersect is called the origin. For a two-dimensional system (x and y axes), the origin has coordinates (0,0). In a three-dimensional system (x, y, and z axes), its coordinates are (0,0,0). It serves as the fixed reference point from which all other points are measured.

• Center is incorrect. While the origin is centrally located within the coordinate plane, "center" is a general term often used to describe the middle point of various shapes (like a circle or sphere) or an object. It is not the precise mathematical term for the intersection of coordinate axes.
• Focus is incorrect. A focus is a specific point associated with conic sections (such as parabolas, ellipses, and hyperbolas), playing a key role in their definition and properties. It has no direct relation to the intersection point of coordinate axes.
• Vertex is incorrect. A vertex is a point where two or more lines, edges, or rays meet. This term is used in geometry for polygons and polyhedra, or for the turning point of a parabola or an angle. It is not the term for the intersection of the primary coordinate axes.
